The Wall Street Journal has reported that Admiral Bill Gortney, head of the U.S. Northern Command, directed on Sunday that recruiting centers nationwide should implement "modest" new security measures as the Pentagon considers more concrete steps in coming weeks and months.

Though Gortney did not authorize recruiters to carry weapons, a point that has spurred debate following a a brazen daylight attack by a 24-year-old Chattanooga man on two military facilities in Chattanooga, they do direct "recruiting centers, reserve centers and ROTC facilities to increase surveillance and take basic steps such as closing blinds at the offices," according to officials interviewed by the Wall Street Journal.

A spokesman for the U.S. Northern Command declined to comment on specific steps when reached by the Journal.
